The Osprey Mutant 52 is a mountaineering pack ready for days spent in alpine conditions and at high altitudes. A narrow profile keeps the Mutant close to the body for comfortable movement. The sternum strap ensures a secure hold, and a reverse-wrap hip belt stows out of the way so you can climb unhindered. A strippable feature set - including the frame sheet, lid, and gear straps - help reduce weight without compromising the 52-litre capacity. Mountain-ready, features like Osprey's ToolLock ice axe attachment, helmet carry net, and reinforced A-frame ski carry will satisfy climbers and ski tourers alike. A snow-shedding back panel and high tenacity recycled NanoFly fabrics ensure four-season functionality.
